CMMC Ecosystem Overview & CMMC Model and Assessment Levels
Map the CMMC ecosystem's key components - DoD, the CMMC Accreditation Body (now ISACA/CMMC-AB transition context), assessment organizations, and the training/credentialing pipeline - into a one-page diagram from memory
Sequence the historical timeline from DFARS 252.204-7012 through the interim rule to CMMC 2.0, noting what changed between 1.0 and 2.0
Distinguish the three CMMC levels by the security requirement source each draws from and the assessment type each requires
Define Level 1, Level 2, and Level 3 in your own words and check each definition against the official model documentation
Your checkpoint
A one-page ecosystem diagram plus a three-row comparison table of CMMC Levels 1–3 (requirement source, assessment type, who assesses)
CMMC Model and Assessment Levels & CMMC Ecosystem Overview
Walk through all 14 domains of the CMMC model and state the purpose of each without notes
Identify which practices belong to Level 1 versus added at Level 2, and which NIST SP 800-171 requirements map to each domain
Explain the difference between a self-assessment and a C3PAO-led certification assessment, including who is eligible for each
Describe the scoring methodology for Level 2 assessments, including how conditional certification and POA&Ms affect outcomes
Your checkpoint
A 14-domain reference sheet listing each domain, its abbreviation, its Level 1 practices, and its NIST SP 800-171 mapping
CMMC Model and Assessment Levels & Defense Contractors and the Marketplace
Trace how a Level 2 assessment is scoped, including which assets and enclaves are in scope and how the boundary is documented
Explain the POA&M process: what can and cannot be placed on a POA&M, timelines, and the conditions for conditional status
Diagram the assessment lifecycle from scheduling through the C3PAO's final report to the affirmation in SPRS
Summarize how assessment results are recorded in SPRS and what a supplier's score means to a prime contractor
Your checkpoint
A process flowchart of the Level 2 assessment lifecycle with POA&M decision points annotated
Ecosystem Roles (Assessors, Practitioners, Instructors) & CMMC Model and Assessment Levels
Differentiate the roles of C3PAO, Certified Assessor, Registered Practitioner, and Registered Practitioner Organization, and state what each is authorized to do
Explain the requirements and conflict-of-interest rules a C3PAO must satisfy to assess an organization
Describe the instructor and curriculum approval pathway for CMMC training, including who authorizes it
Practice explaining the assessment process aloud to a non-technical colleague in under five minutes
Your checkpoint
A role-permission matrix covering C3PAO, Certified Assessor, RPO, Registered Practitioner, and Instructor, with authorization limits for each
Ecosystem Roles (Assessors, Practitioners, Instructors) & Defense Contractors and the Marketplace
Outline the steps an organization takes to prepare for a C3PAO assessment, from gap analysis through evidence collection
Describe how a defense contractor selects and engages a C3PAO, including independence and scheduling considerations
Explain what a prime contractor must do to flow down CMMC requirements to subcontractors and how that affects the supply chain
Identify common pitfalls that cause assessment delays or failures
Your checkpoint
A one-page preparation checklist a defense contractor could use before engaging a C3PAO
Defense Contractors and the Marketplace & CMMC Ecosystem Overview
Explain how CMMC requirements appear in solicitations and contracts, and which DFARS clauses trigger them
Describe the SPRS scoring system and how a score is calculated and maintained
Map the marketplace of CMMC service providers: consultants, MSPs, RPOs, and C3PAOs, and how they differ
Analyze a hypothetical small defense contractor's situation and recommend a path to compliance
Your checkpoint
A written scenario analysis recommending a compliance path for a hypothetical small defense contractor, with reasoning tied to the model
CMMC Ecosystem Overview & CMMC Model and Assessment Levels & Ecosystem Roles (Assessors, Practitioners, Instructors) & Defense Contractors and the Marketplace
Review all four domains using spaced repetition and identify your three weakest subtopics
Create 20 practice questions across all domains and answer them without notes
Re-explain the CMMC 1.0 to 2.0 changes and the three levels from memory
Walk through the full assessment lifecycle end-to-end from memory in under ten minutes
Your checkpoint
A scored 20-question self-test with a written list of your three weakest subtopics and a remediation plan
CMMC Ecosystem Overview & CMMC Model and Assessment Levels & Ecosystem Roles (Assessors, Practitioners, Instructors) & Defense Contractors and the Marketplace
Close remaining knowledge gaps identified in week 7
Complete a timed full-length practice exam under test conditions
Review every missed question and write a one-sentence correction for each
Confirm exam-day logistics and finalize a one-page summary sheet of key facts
Your checkpoint
A completed timed practice exam with a written error log and a final one-page summary sheet
Milestones
Week 4: Can explain all three CMMC levels and the difference between self-assessment and C3PAO certification without notes, scoring at least 80% on a 15-question self-quiz
Week 6: Can describe the roles of C3PAO, Certified Assessor, RPO, and Registered Practitioner and how a contractor engages each, verified by explaining it aloud to a colleague or recording
Week 8: Score at least 85% on a timed full-length practice exam across all four domains
